DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 310,752, dated January 13, 1885. Application filed April 11, 1884. (No model.)

To 04% whom it may concern:

Be it known that I, ALONZO B. WALKER, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Door Checks and Locks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which Figure 1 is a rear side view. Fig. 2 is a front side view showing the parts in position for looking a door. Fig. 3 is a trans verse sectional View on lines xx, Figs. 1 and 2. Fig. 4 is a detached View of plate. Fig. 5 is a view showing my improvement used as a door-check. Fig. 6 shows my improvement used as a window-catch.

This invention relates to that class of door and window checks consisting. of a disk eccentrically pivoted to a door or window-sash in such manner that the disk may be swung into position to engage the door or window" frame and prevent the same from being opened or raised, and has for its object to provide a simple, cheap, and durable check that may be readily applied to a door or window, as may be desired.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the drawings, A indicates an eccentric,

' the periphery of which is provided with two projecting flanges adapted to embrace and securely hold in place a rubber band or tire, G.

B indicates a washer-plate, having on its back or under side pointed projections b, which enter the wood when the check is screwed in position and prevent the said plate from turning. Said plate B is perforated centrally to receive the screw D, which secures the eccentric in position.

G indicates a lug made in one piece with the plate B, and at right angles to but in the same plane with said plate. The eccentric A is provided upon its rear side with a lug or projection, H, adapted to come in contact with the lug G when the eccentric has been rotated a certain distance, as will be clearly seen in Fig. 1 of the drawings, and thus prevent said ec'centricfrom being rotated farther than a predetermined distance.

F indicates a keeper provided with a slot adapted to receive the periphery of the eccentric when swung into position for locking. Said keeper is designed to be secured to the door-frame in the ordinary manner.

For convenience of turning the eccentric, I provide the same at or near its periphery with a knob, E.

In operation the eccentric is pivoted by means of the screw D to the door, near the lower corner of the same, and in such position that when the eccentric is turned down to its lowest position it shall project down below the lower edge of the door.

It will be readily understood that the keep er F is applied to the door frame at a point directly opposite the eccentric when the door is closed.

The door may be held in any desired position by turning the eccentric to its lowest po sition, so it will comein contact with the floor, the rubber tire creating agood frictional contact with the same.

WVhen the door is in its closed position, the

eccentric is rotated until it enters the keeper F, which effectually locks the door against entrance from the other side.

It is obvious that the device may be employed as a window or sash lock or fastener by pivoting the eccentric to the window-sash, instead of to the door, and in such case the keeper may be dispensed with, as the eccentric will bind against the window-frame when turned to the proper position and effectually prevent the same from being raised.

Having described myinvention, what I claim 1s-- The eccentric A, provided upon its rear side with the lug H, in combination with the washer plate B, having lug G, and provided upon its rear side with pointed projections b, said eccentric and washer-plate being pivotally connected to each other, substantially as described and shown.

I11 testimony that I claim the above I have hereunto subscribed my name in presence of two witnesses.
